'GLXPlatform' object has no attribute 'WGL'

I'm a beginner in OpenGL/OpenCL. I'm trying to execute code from this example, but there is an error:

Traceback (most recent call last):
File "/home/anka-rybalko/workspace/bla/openGL.py", line 99, in initializeGL

AttributeError: 'GLXPlatform' object has no attribute 'WGL'

As I understand, WGL is an API for Windows OS and not for Linux. Should I somehow specify my platform before? Or how can I fix this?

Thanks in advance!

Solution

The code you are using (PyOpenGL 2014.1) is importing two platform-specific modules (WGL and GLX). PyOpenGL should have raised that error as an ImportError (rather than the AttributeError), but it still would have failed.

PyOpenCL has, in the meantime, worked around the issue in their github repository. If you have git installed (and pip) then this should get you a new version (note: not set up for OpenCL development here, so can't actually test this):

pip install git+https://github.com/pyopencl/pyopencl#egg=pyopencl
